Answer: 6.24 km
Explanation:
Given
The magnitude of the first vector(say)
the magnitude of the second vector(say)
the angle between them is
The resultant vector magnitude is given by
Answers:
a)
b)
c)
Explanation:
We have the following data:
is the spring constant
is the amplitude of oscillation
is the velocity of the block when
Now let's begin with the answers:
<h3>a) Mass of the block</h3>
We can solve this by the conservation of energy principle:
(1)
Where:
is the initial potential energy
is the initial kinetic energy
is the final potential energy
is the final kinetic energy
Then:
(2)
Isolating :
(3)
(4)
(5)
<h3>b) Period</h3>
The period is given by:
(6)
Substituting (5) in (6):
(7)
(8)
<h3>c) Maximum acceleration</h3>
The maximum acceleration is when the force is maximum , as well :
(9)
Being
Hence:
(10)
Finding :
(11)
(12)
Finally:
A neutral atom is simply an atom that has no charge.
